.To all whom it may concern:

Be it known that I, GAEsAR R. BANNIHR, a citizen of the United States, residing at West Cheshire, in the county of NewHaven and State of Connecticut, have invented a new and useful Machine for the Purpose of Engraving and Carvlng Buttons, of which the following is a specification.

My invention relates to improvements in button ornamenting and carving machines, where, by means of milling cutters or drills, the surface of a button may be engraved or carved; and the objects of my improvements are, first, to provide a universal means of indexing, which will present any desired part of the surface of such articles. as buttons, knobs, checkers, &c., whether of ivory, pearl, wood,

positions, to a special milling cutter, drill, or gr nder; and,'s econd, to afford facilities for bringing such cutters as named above to bear on the desired parts of the article to be orna 2, a front view of the same; Fig. 3, a top view.

of that part comprising the indexing device, with the positions of the spindles shown by dotted lines. Fig. 4 shows the under side of the same.

ing-cutters, &c. Fig. 6 shows a top and sec tional view of the rotary cylindrical index and chuck. Fig. 7 gives .the side view of three milling-cutters and the top view of a button cut with them. Fig. 8 is a sectional view, on an enlarged scale, of the cylindrical index, showing the manner of indexing. Fig. 9 presents a top View, on an enlarged scale, of the index-arm,with universal indexing device containing a chuck holding a button. Fig. 10 is a side view of the same, showing the positions of the horizontal revolving index in relation to the vertical circular index.

Similar letters refer to similar parts throughout the several views.

The base B, shaft A, and spindle-arm 0 constitute the frame of the machine. The spindle-arm G is secured to the shaft A by a set- ,moving the lever O by means of a roller-pin Fig. 5 shows the top of the arm that holds the spindles which carry the milln/fil screw drawing together thesplit, hub table of index-arm D turns onthe s'haf ,7 U1 is held in position by the collars LandM he collar L having a flange, on the edge off, ch are notches for the pawl K to fall into inchan v ing the arm D from one spindle to another, On the under side of the flange is an annular groove, S, on an eccentric, for the'purpose of in the groove S, connected with the slide P. To the'lever O is connected the sleeve N, which has at the other end the spring h, which by this mechanism will be moved up or down as the arm D is moved right or left, so that it may engage with a different spindle and index at the same time. On the other or outer end of the index-arm D is the device for holding the article to be worked upon, as in the drawings it is a ballbutton, d, which is held by the chuck c. This chuck is placed in the cylindrical index F, which has a bearing in the box E, which has on the side toward the index-arm D the circular index G, and in the center of this is the shaft on which it turns, the shaft passing through the index-arm D and is held in place by the nut and washer on the end.

The index G consists of a hardened-steel ring with notches on its periphery, into which the pawl H catches,wl1i'ch is held down by the spring I, the steel ring having notches of different divisions on its edge, and may be changed so as to have the notches come under the pawl by changing the set-screw Z into different holes in the hub, between the boxE and arm D; and if more divisions are needed than one ring will admit of it is so arranged that the ring can be taken off and replaced by one with the required divisions. In this way any number of divisions may be had in the index. The pawl H has a V-shaped projection, which drops into the division-notches in the ring G.

, The manner of indexing with this device is to represented by indentations or drill-holes 75,.

as shown in Fig. 8. The pinsj,of which there are as many as there are rows of divisions on the index-cylinder, and which have a conical end which enters the holes L as they are brought under the pins when the cylinder is rotated or moved from hole to hole, which is done by turning the handle a between the forefinger and thumb of the operators left hand. The pins j are .forced against the cylinder F by the action of the spring h as it is brought to bear on these ends, as is shown in Fig. 8, either as the arm D is moved from spindle to spindle, as hereinbefore described, or as the index G, in connection with the box IE, is turned upon its axis, as shown by the dotted lines in Fig. 10, and as the holes in the cylinder come under the pins the spring it will shove them in and will also hold the cylinder F, containing the work,from turning while the cutting of the article is being done, and when done the cylinder F is turned to the next hole, and in doing so, by means of the two inclines of the drill-hole in the cylinder and the conical end of the pin, the pin is forced out, and as the cylinder turns by the action of the operators hand, as before said,the pin being forced against it will enter the next hole, as already stated.

The means provided for keeping the pins which are not in use in position and from entering the holes is the spring 2', having a slot in the end to receive the pins by the groove. (See Fig. 8.) Between each two pins this spring has a split, so that each pin in reality has a spring of its own, which is only strong enough to keep the pin on which it acts in position, and will yield to the action of the spring h as it is brought to bear upon it by its movement up or down or by the rotary movement of the box IE, and by the inclined or curved shape on the inside it will slide upon or pass over them. (See Fig. 8.)

The spring h, in connection with the pins on the under side of the box IE, works in a similar manner by the action imparted to the pitman Q by the lever O. \Vhen the index G is used, the pitman (g is disconnected.

The method shown in the drawings for holding work is mainly for buttons, and consists of the chuck 0, having a slot through its central part, through which passes the hook, which hooks into the eye of a button and draws it into the chuck by the action of the spiral spring g on the other end of the hook-rod which passes through the stem F. (See Fig.

6.) The button f is for the spring g to act against and to push up on when taking the work from the chuck.

The spindles a a a are to carry the millin g cutters, drills, or grinders, as the case may be, or act as a slide by which a horizontal spindle, b, with tool, is brought to act on the work in a similar manner as the other two, I) b, are by pressing on the button on top of the spindle with the fingers of the right hand, while the left hand manipulates 'the indexing by the handle 0. The spindles are brought up by the action of the spring between the top bearing and the button or knob on its top end, which is loose and held in place with a screw.

The belt which is to impart motion'to the spindles carries the pulleys,which are splined. The spline works in a groove in the spindle.

The horizontal spindle I), with cutter, may be used in any of the spindles by setting the same by means of the pin in, which passes through the casting and into a hole in the pulley, thus keeping it from turning. The pulley on the end of the horizontal spindle b is driven by a belt similar to the others, and when the cutter connected therewith is to be used it is brought to the work, as before described.

Having described the mechanism and far cilities of this machine, it will be seen that by supplying different milling cutters or grinders almost an endless variety of designs may be wrought in as many kinds of material as are used in the arts to which this mechanism is applicable. 4

I am aware that such parts of this machine as the arm 0, with the gang of spindles for drilling or milling, is not new, nor is the combination therewith of a swinging table 011 a column. I therefore do not claim such a combination, broadly; but

hat I do claim as my invention, and desire to secure by Letters Patent, is
